Lines on picture from t2

Hi, I have issues with my pictures that I load from file. Some have lines missing or if photos then starts out great but finishes poorly. My line art is good. What do I need to do to sort photos and pictures please?

@magictoolbox I'm not sure what you are saying, are the files not loading correctly or there is a problem with the laser output? You can check the simulation "view" to see exactly what is output to determine if it's a laser issue or not.

It actually sounds like the laser is failing when it gets hot, but please upload pictures or send your question to support@t2laser.org email.
